In January 2012, HBO started airing Lena Dunham's "Girls," a meditation on the awkwardness of being female and 20-ish in New York. By year's end, actress-director-writer Dunham, at 26, gathered so much buzz -- even appearing naked at the Primetime Emmy Awards -- that she was on her way to becoming what her character, Hannah Horvath, can only dream of being: "The voice of my generation. Or at least, A voice. Of A generation."

The year's worst-kept secret was the popularity of the steamy "Fifty Shades of Grey" trilogy among suburban soccer moms. Sales for E.L. James' "mommy porn," which started out as "Twilight" fan fiction, topped 10 million, making it among the fastest-selling series of all time. Even a ban on the books at some public libraries failed to dampen sales. So lucrative was the book that publisher Random House gave all of its employees a holiday bonus this year.

Suddenly in December, the term hyperemesis gravidarum was on the tip of everyone's tongue, thanks to a yet-to-be-born British heir. The rare ailment is an acute form of morning sickness and made headlines when Kate, Duchess of Cambridge, was admitted to a London hospital for treatment of it.

Joy over the impending arrival of a royal baby was marred by a radio hoax in which two Australian DJs, posing as Queen Elizabeth II and Prince Charles, made a phone call to the hospital to get information about the duchess' condition. One of the nurses who handled the call later took her own life.
